INHALER AND DUST-PROTECTOR.

Specification of Letters Patent.

Patented Mar. 18, 1919.

Application filed January 4, 1916. Serial No. 70,244.

An object of my invention is to provide protector comprising a shieldmember which may be fitted in place over the mouth or nostrils, or both,and which has a space to receive wool or other filtering material sothat upon each breath, the air will be strained and filtered, and if amedicament be applied to the filtering material, the air will carry thesaid medicament into the lungs in the form of a. vapor.

A further object is to provide means to secure the shield in place,which means is constructed to permit adjustment to adapt the device foruse by various persons.

With other objects in view, my invention consists in certain novelfeatures of construction and combinations of parts which willhereinafter be set forth in connection with the accompanying drawingsand then pointed out in the claim.

In the drawings:

Figure 1 is a View showing the manner in which the device is applied andheld in place.

Fig. 2 is a view in elevation of the shield.

Fig. 3 is a view looking into the shield.

Fig. 1 is a detail view of the means by which the securing cord may beadjusted.

Fig. 5 is a plan View of a modification which may be resorted to inconnection with the shield.

In the form illustrated in Figs. -1 to 3 inclusive the shield 1 may beconstructed of aluminum, hard rubber, or other suitable material. Thisshield is cupped out to form a filter chamber which is preferably madeof substantially elliptical form the edges of the cupped portion rolledover as at 2, and shaped to fit against the face over the nostrils andmouth, as is better illustrated in Fig. 2.

The cupped portion 3 of the shield has th perforations 4c formedtherethrough to permit the supply of air to the interior of the shieldand to also permit the escape of air therefrom. and if desired, a crosspiece 5 may be disposed between the top and bottom sides of the cuppedportion adjacent the rolled edge to aid in retaining the-wool or otherfilter material indicated at 6 in Fig. 3.

'With the parts arranged in the manner hereinbefore set forth, therolled edge 2 of the shield member may be fitted against the face overthe mouth, the nostrils, or both, and as all air taken into the lungsmust pass through the perforations 4 and consequently through the woolor other filtering medium shown at 6, the air will be strained andfiltered of impurities before being taken into the lungs,

and also the breath passing from the mouth and the nostrils will causethe fibrous filtering medium to be warmed and as the next breath isdrawn in through the shield the air will be warmed and brought to atemperature more nearly approximating the temperature of the body thandoes the temperature of the atmospheric air.

, As a means of securing the shield in the proper position, the springclips 7 are provided to be received over the ears and at their forwardends have the eyes 8 provided. A cord 9 is passed through an opening 10on each side of the shield 1, and these cords are led through the eyes 8of the spring clips 7 and are brought back to be secured with thes-shaped adjusting members 17 which are received around the main extentof the cord 9. In fitting the shield to be secured in place, the shield1 is positioned at the proper point, the spring clips 7 are fitted overthe ears, and the adjusting members 17 are then moved to bring the cords9 to the proper tension, these adjusting members 17 being in engagementwith the body of the cords 9 to bind sufficiently to retain theadjustment thus made.

The filtering medium 6 has been referred to as wool or an equivalentsubstance, but when occasion requires this material might be one whichwould have medicinal properties or the wool or other filter material maybe saturated with a medicament which will be taken up by the air passingtherethrough and will pass with the air into the lungs, in the form of avapor.

While I have herein shown and described only specific forms of theinvention, it will be understood that the cord 9 might be an elasticcord, that the shield portion might be constructed of celluloid or someother material not herein described, and that other modifications mightbe resorted to in materials used and in the construction and combinationof parts Without departing from the spirit and {scope of my invention,

. and hence I do not Wish to be limited to the exact invention hereinillustrated, but only to such points as may be set forth in 'the claim.

I claim:

v In an inhaler and dust collector, the combination of a perforated bodyportion, said I body portion being longitudinally channeled of, a Washerresting upon said rim, said 15 Washer being curved throughout its entirelength to conform to the contour of the rim, said Washer being providedwith openings, said bar reinforcing said washer, intermediate its ends,and retaining means connected to said body portion.

In testimony whereof I afiix my signature 1n presence of two witnesses.
